Questions tagged [teneo]

Teneo provides integration with EclipseLink to support persistence of arbitrary EMF models with JPA.

The original goal of this integration was to allow developers to map EMF generated classes with standard JPA to existing databases (so called 'meet-in-the-middle' mapping). This is an important feature if you're building an application on an existing database. However Teneo also supports a full model driven development approach that supports generating the classes, JPA mappings, and database schema from an EMF model.
